HEATER FOR GASOLENE-SUPPLY PIPES.

Application filed July 30,

To all whom t may concern Be it known that l, EDGAR ltlrLLNnR. a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Heaters for Gasolene-Supply Pipes, of which the following is a specication, reference being had to the accompanying drawing, forming a part thereof. j

This inventionrelates generally to heating devices and, more particularly, to a certain new and useful heating attachment for the tube or pipe that leads from a gasolene or other hydro-carbon supply tank or reservoir tov a carbureter or `other vaporizing device, or to a burner, and the like.

It is generally known that inthe operation of internal combustion engines, and particularly during the colder months of the year, the carbureter does not always function properly, due to the fact that the gasolene delivered to it is comparatively cold and, therefore, will not vaporize readily; and it is one of the principal objects of my invention to provide relatively simple and ellicient means for materially increasing the temperature of the gasolene, preferably at a point in the supply pipe closely adjacent to the carbureter, thereby facilitating and insuring' more perfect vaporization of the gasolene, or like volatile Huid, as it enters and passes through the carbureter.

With the foregoing and other objects in view, my invention consists in certain novel features of form, construction, arrangement, and combination of parts hereinafter more fully described and claimed and illustrated in the accompanying drawing, in which- Figure 1 is a vertical section taken lengthwise through the center of a heating' device embodying my invention;

F ig. 2 is a cross-section taken approximately on the line 2`2 of F ig. 1; and f F ig. 3 is a cross sectiontaken approximately on the line 3-3 of F ig. 1.

' eferring by numerals to the accompanying drawing, whichy illustrates a practical embodiment of my invention, l0 designates the gasolene supply pipe. or tubethat leads from the gasolene-supply tank or reservoir to the carbureter, and my improvedy heating device is especially adapted for attachment upon this pipe, preferably at a point closely adjacent to the carbureter.

It is to be understood that, while my new Vheating device Yis particularly adapted for Specification of Letters Patent.

use, and is herein shown and will be described in connection, with the gasolenesupply pipe of an internal combustion engine, it may be equally well used in connection with other hydro-carbon supply pipes leading to burners and the like.

My improved heating device as shown includes a substantially tubular body 11, preferably formed of Hexible material, such as fabric or a combination of fabric and rubber, or the like; and secured in any suitable manner to the ends of this tubular body are heads 12 and 13, preferably formed of suitable insulating material, such as fiber.

Theheads 12 and 13 are provided with centrally arranged apertures 1/1 and 15, respectively, for the accommodation of the supply-pipe 10; and seated in the head 13, which is substantially longer than the head 12, is a set-screw 16, which provides means or securing the heating` device in position upon the gasolene-supply pipe.

The tubular body 11is somewhat gr ater in diameter than the supply pipe 10, in order to form or provide a heating chamber 17, of suitable area, around that portion of the pipe 10 inclosed or embraced bemember thin and suitably sheet asbestosv or other analogous material, which serves as a support for the heating element, the latter being in the form of a resistance coil 19. his coil encircles the tubular member 18 and occupies the relatively narrow annular space between the tubular body 11, the terminal portions 20 of the resistance coil 19 extending into small metal tubes 21 that are seated in head 13. These terminal portions of the coil are irmly secured in the tubular members 21 by means of set-screws or the like 22, the same being screw-seated in the head 13, and their inner ends bearing against the terminal portions 20 within tubular members 21.

The electric vcurrent for heating the resistancecoil may be obtained from any suitable source of supply, as, for instance, by means of conductors 23, which' lead from a battery 24 tothe outer ends of tubular members 21, said conductors being secured in said tubular members 21 by suitable setscrews 25.

To maintain the tubular member or shell 18 in suitably distended and in spaced relation throughout `from the embraced pipe, and also provide a firm and substantial support for the resistance coil, suitable spacing rings or Vwashers, such as 26, are ar-Y ranged upon the supply pipe 10'` within chamber 17 and the outer edges of said spacing members bearing directly against the inner surface of the tubular member or shell 18.

When in service, the electric current from battery 24, or other source of-supply, passes through resistance coil 19, thereby heating the same, and in a very short time the air within chamber 17 will be heated, with the result that the gasolene passing through pipe 10, and which latter passes through vheating chamber 17, will be pre-heated just prior to its delivery to the carbureter.

lt will be understood that my improved heating device is not intended to heat the gasolene in the supply pipe to Such a degree as to effectV vaporization, but, on the other hand, the gasolene passing to the carbureter will be heated to such a degree as will insure its rapid vaporizationr While passing through the carbureter, and which result is highly desirable, particularly durin relatively low atmospheric temperatures. bviously, a suitable electrical switch can be located on either one of the conductors 23, thus forming a heating device to be turned -on or oli at the will of the operator.

A gasolene heating device of my improved construction is comparatively simple, isV

capable of being easily and cheaply produced, can be readily installed, is economical in point of current consumption, and is very etective in pertorming'its intended functions.

It will be readily changes in the size, of the various parts ot my understood that minor Jform and construction improved heating device may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

Having thus described my invention, what l claim and desire to secure by Letters Patent is:
